Title: Draw the colormap with a polyline --> antialiasing

Currently the LUT lines are drawn with sequences of one pixel lines. This patch
replaces that by polylines that go through all control points. I think polyline are faster, and more
importantly, it produces nice antialiased lines !

Here is the result:

The code also adds a getter for the rawData property in IcyColorMapBand, and fixes the copy of that parameter when copying from another colorMap.
